Hi i have a twin shower pump that only increases pressure at shower

Is there any way using the same pump to increase the flow to the bath by somehow linking to hotwater outlet on cylinder

I have an indirect cylinder

You have gravity fed hot and cold feeds?

Is your shower pump currently connected to a thermostatic mixer shower?

Where is the shower pump sited?
 
Probably the easiest way would be to disconnect and/or cap the current hot water supply to the bath and connect it to the shower supply pipe from the pump.

That being said, issues can easily be introduced when DIY'ing with pumped supplies.
 
I used to have 2 showers connected off one pump and it worked fine... Even OK when both running. As above just T off the pump outlet pipes and then elbow into the bath feeds having capped off the old feeds as near as you can to the carcassing so that you don't leave long deadlegs full of uncirculated water (150mm from where they Tee off now).

1. When you have a shower you mix hot and cold, so both sides of the pump has water in it.
2. When you run a bath you may run hot and cold separately. When this happens, one side of the pump has nothing in it.
3. The pump uses the water to lubricate the bearings, so the side with no water will spin, but without lubrication. Pump won't last.

That why a lot of the the newer dual pumps have an internal bypass, it allows water to circulate from the closed to the open end, when one side is running against a closed circuit, so it gets circulation and doesn't overheat.
